Essentially, all motors are incompatible with Labview. Motors are just motors, and Labview is just software. A servo motor is connected to an amplifier(drive), and the drive is connected to a motion controller. The drive and motion controller can be one unit. Almost any drive or motion controller that has communications can be controlled from Labview. Some suppliers offer Labview drivers for free or for purchase. Some that come to mind are Delta Tau, Galil, and Parker(ACR series). Of course, the most "Labview compatible" controllers are those sold by National Instruments. You will still need to select a motor and drive, though.
If you have an application in mind, please tell us about it and be will be able to point you in the right direction.
